' -My invent-ion relates to machines for excavat1ng, d'1tch 1ng',etc., of'the'class in which anendless chain 'ofbucket's and forks, supported/upon-and suspendedfrom a suitable and vertically movable framework and driven by an engi elevating, and. discharging'the material.

"The-present machine is particularly well A adapted for excavating sewers and for leveling ground by cutting away the face of, banks or hills. f

The excavator may be generally described. as consisting of a baseframe mounted'upon suitable carriage wheels so that it may 'run V; [on temporary tracks which are held on the ground at the-pomt where theexcavation or '25 .cueisto' be made. .Carried'u'pon the base.

Fi gfi9 is an enlarged-detailed'perspective view of the '70 upper end of the beams showing the manner in which they are supported from the cross shaft.

In the; drawings like characters of reference lndlcate corresponding parts in each figure, 1 is .a rectangular base frame supported forwardly and rearwardly on wheels-2 and 3, the Wheels being shown of .sufiicient width to carry the weight of the excavator without sinking into thegroun'd. If it be so de-, sired otherfianged wheels could be used.

when temporary rails are laid on the ground.

4 is a rectangular platform super-imposed above-the'base frame and it is so attached to the frame that it may rock if required. Inorder to allow' of this Ihave distributed several similar transverse racks along the base frame and have secured on, the under base of the platform oppositely curved graclrs 6 which rest on the-lower racks, the

upper racks havingside flanges 6' 'in order toreve'nt longitudinal displacement of-th platform. L

rear end of the platform being supported by '7 is a canopy or housing erected on the.

uprights 8 and serves the purpose. of protecting the motorengine 9 from rain, snow or hail. The engine maybe of any suitable form, that; shown being a gasolene engine, of which lO is the niainshaft ll' the flywheel, and'12 the drive pulley;

13, 14,- 15 and 16 are upright beams'suitably-fastened at their base to the platform 4 at its forward end, such beams being inter connected by upper horizontal longitudinal and cross beams 17 .and 18, respectively.

The inner set ofjbeams 16 have longitudinal grooves 16 cut thereinforminga guideway or track for sets of rollers later explained. There are two'of these latter-beams at; 6 th side of the platform 4 andthose at one side.

are directly opposite those at the other' as shown. The beams 13 and 14 are simply for the purpose ofstrengthening the structure;

-()perating in the tracks or'grooves supplied in the beams 16 is a carriage 19 which is formed .from two horizontally extending,

beams 20 which extend both forwardly and to the rear of the beams l6 and are located directly to the inside of the vertical beams. The beams20 have secured to them by means of cross strips 21 an upper and a lower short beam 22. The beams 21 are spaced apart a distance such'that their one face outclears the inner face of the beams 16, in this are bear ng brackets secured firmly to the uprightbe'ams 8, directly opposite each i other, and they receive a counter shaft 27 on which is mounteda bevel gear '28.

' the usual way. j

31 and 32"are horizontal beams passing between the vertical beams 8 and 15, and 33, 34,are standards passing between the beams 3lan-d the pla tform 4. a p

35 and 36 are suitable cross members secured to'the opposing 'sets of beams 33 and 34.

' 37 is a shaft mounted infsuitable bearings v through a cross beam 43 which is supported by the platform 4, as shown, there being two small blocks44 inserted between the ,platform' and the beam, at either end, toraise the level of the beam, for a reason which will afterward appear.

4-5 is a bevel pinion firmly secured to the shaft 41, and 46 is'a be'vel' wheel at the opposite end of the shaft 37 the p n on 40. This latter pinion meshes with the pinion 45. 47 is a plate passing between the beams'l8 directly abovethe carriage 19.

The bevel wheel 57 is designed with either of the bevel pinions 58 and *59,

"and reverse motion.

its providedxwith a stationary as through which passes theshaft 50 and on account of this the turning of the shaft forces the carriage 19 up or down as desired according to the rotation.

' 52 is abevel pinion on the lower end of the screw shaft 50 and beneath the cross beam 48.

. 53 is a bracket secured to. the under face of the platform, and 54 is-a shaft having its one end bearing within: the bracket and the other end-within a suitable bearing {)5 carried by the forward cross member :of the platform 4.

56 is a bevel pinion secured onj the shaft 54'and positioned so thatit Will mesh with the bevel pinion 52. I

57 is a bevel wheel at the lower end'of the shaft 41 immediately beneath the cross beam 43. i

aaoyss at the opposite ends of the shaft 72, such 1 gear wheels being oppositely disposed and f bolted. to, the beams and pass over and preventing rotation. The beams 77 are held a proper distance apartby means of interposed cross braces 7 9. At the lower end of each of the-beams 77 I have provided an adjust-able plate 80, such plates being slotted and held to the beams by means of belts or pins 81 onwhich are placed nuts 82 which may be loosened or tightened for adjusting purposes. 1

83 is across-shaft carried in suitable bearings provided in the plates 80, the shaft being-parallel with the upper-"shaft. 72 and m the normal position directly beneath it.

8.4: are two circular disks securedto and centered on the shaft 83, being placed on the shaft directly against the outer face of the plates 8.0, and consequently directly in alinement with the gear wheels 74.

' 85 are endless gear chains operating on the disks 84 and the gear wheels 7 6. Each chain is composed of a series of similarmter-con- ."nected links 86 of the form shown in per.- speetivedetail in F 1g.- at of the drawings;

It'will be 11oticed' 'that each link has on its upper face and centrally a cross channel 86; cuttherein. The chains are interconnected by aseries of cross plates 87 which are of'a length somewhat greater than the distance between the gear wheels ordisks, that is the plates extend slightly beyond the chains at either side. manner fastened securely to the individual links of the chains, such as by bolts or rivets,

C(ll'lllfifiifld' to the plates at regular intervals and adapted to operate with-them are scoops or'buckets 88, having an open front and a closed curved back. and bottom. Connected to others of the plates. at regular intervals and disposed in each case between each successive pair of buckets are curved rakes or cutting bars 89. )n each plate there are several cutting arms and their purpose 18 to pierce and break the earth to. be excavated when the chains are revolved in the direction noted by the arrow in F 1g. 1. The earth which-is in this way loosened is picked up by the buckets and carried to a suitable v In this way the beams are free to be swung forwardly or back-. Wardly on the shaft and without binding or The plates are in any suitable brackets a which are fastened pinion at the upper end of th .and meshmgwlth the bevel whe 0 IS a bevel pin on'on the sh 5) me nng with the bevel pinion 94km su '1 anianne'r 90 and extending "ment of. an arc .point', laterexplained, where itis transferred p H i ton-set of carriers or .conveyers. The adthe straps-sand adaptedto. screw against the 130 vantage in having the ends of the plates 87 extend beyond the chainsis so that the chainsmay be carried onthe gear wheels and disks.

Referring to the drawings it will be seen that the teeth of'the gear wheels pass between the adjoining endsof the plates, or in other words the ends of the plates. rest in the opening between the teeth; The plates simply rest onv the face of the disk wheels as it is unnecessary to have any further drivmg means other than tl'ie'gear wheels. It is particularly to be noticed that. the links are not-provided with the ordinary recess to receive'the teeth.

.90 are a set of beams secured to the forward end of the beams 20 and extending therebeyond an equal distance.

' 91 are brackets secured to the outer face i of the beams toward their ends there bein a set of brackets on each beam. 92 1s a roller. suitably mounted in bearn'igs Carried by one pair of the brackets 91, and. 1 93 15a shaft mounted in bearings formed in the other set of brackets 91.

1.5 cleats or bars disposed on the chains between the scoops and the hooked bars. They may be designed in the form of a hinge with a short wing, the short wing being. bolted or otherwise fastened in each case to the cross plate. 87, intervening between the plate carrying one of the hooks, and thatcarrying one of the scoops. The advantage ga ned by usingthese deflector plates is that of directing the earth carried up and thrown down by the scoops onto the endless belt 96. His to be noticed that the deflector plates on the side of the endless chains toward the platform are hanging vertically, and that they lie flat. against the chains until they pass over the gear wheels 76 and commence to descend. The deflector plates after passing over successively swing into a position such that they rest on the upper side of the adjoining set of hooked Consequently the material thrown down by the scoop directly above is received by the plates and directed to the belt 96 where it is immediately transferred to' the belt a and discharged.

If it is desired to have theexcavator propel itself in so far as moving from point to point is concerned, any suitable system of gearing and drive'chains can be used, such interconnecting the counter shaft 27 with the carriage wheels 3.

In order that the platformv at may be rocked in respect to the base frame on the tracks I have provided a set of vertically extending rods 9 which are loosely connect- -ed to the, base frame and pass up through an elongated opening provided in the platform. Where the rods pass through the platform I have placed a plate 1" and upon each rod, which .it willbe understood is already threaded, is provided a hand wheel 8. Consequently the platform 4 can be placed at the desired incline by screwing down the hand wheels at one side of the frame and releasing those at the opposite side of the frame. Various other well known means may be employed which would serve the same purpose as the hand wheels and rods and I wish it to bc undr ood that such may be ap 'ilied, if it be found desirable, without departing from the spirit of my invention.

In usii'ia' mvmachine for excavating sewers,.ccllars, or such like, it will be operated as'fol'lm s;--\ssuzning the engine started, it will be seen that with the interconnection as shown in Fig. 1, the scoops will be rofdrive connection for the shaft 63.

1 in this manner holding the bars j at l ing arrow. The hook ed arms will breaktnc surface soil and the scoops will collect it and later deposit it on the endless belt which is turned in a direction which will carry material thrown thereon to the second belt. It in turn, on account of the interconnections with the shaft 72 will deposit the earth received over the free end. As the earth is excavated and leveled the carriage 19 is lowered in position and this is controlled by the lever 61.

lVith the lever in the position shown in F l the carriage will descend and with it in the reversed position the carriage will ascend; Consequently the depth to which one can excavate with my machine will depend entirely upon the distance to which the carriage can be lowered, as will readily be seen.

lVhere it is required to cut away the face of a bank or bill the lower end of the beams 77 would be swung outwardly and the hooked arms would break down the face of the bank while the scoops would carry away the material loosened.

Considerable advantage isgained by having the platform rockable on the base frame as it allows the excavator to be used with equal facility on slanting or sloping ground, as the upper platform can be set to always remain in the horizontal position. Conse-' quently the scoops and hooked arms will always be in a position to work to the best advantage.

Particular attention is directed to the manner in which the carriage is rendered adjustable vertically while still retaining a The square shaft 11 and the bevel wheel 68 slidable on the shaft and rotatable therewith allow of this combined vertical adjustment and drive.
